Abstract

The utility model provides a hard pen with an elastic acuate cover. The internal part of a penholder is provided with a pen core with elasticity, simultaneously, an elastic body is arranged at the front end of the acuate cover connected with the head part of the penholder; and the rear end of the acuate cover is provided with a rigid component which is provided with internal threads connected with the threads of the penholder. The acuate cover is formed by the secondarily injection modeling of the elastic body at the front end of the elastic body and the rigid component at the rear end of the acuate cover. By adopting the scheme, the elastic acuate cover can be effectively and fixedly connected with the penholder or a thread connecting piece, and the appearance is beautiful.

Description

A kind of point cover rubber-like hard-tipped pen

Technical field

The utility model relates to a kind of writing pen, especially hard-tipped pen such as ball pen, gel ink pen, signature pen.

Background technology

Present known elastic hard-tipped pen, see " a kind of elasticity point cover hard-tipped pen " of Xu's root China utility model, the patent No.: 200620156403.6, penholder point cover is by the elastomeric material manufacturing, but because this point cover of being made by elastomeric material can't connect with penholder by screw thread, and it is bonding to need to pass through artificial glue, so just is unfavorable for the stable of mechanization production and product quality.Simultaneously, pen is to use the very high commodity of frequency, and penholder and elasticity point cover can be subjected to the various power such as pressure, torsion, folding power of various aspects in long-term use, and elasticity point cover is being bent always, at this moment, the point of attachment of elasticity point cover and penholder or thread connector will become flexible and come off.

Summary of the invention

The purpose of this utility model is to provide a kind of elastomer effectively firmly to connect with penholder point cover hard part, and it is more comfortable to write feel, and capable more smooth and easy, writes for a long time and do not allow fatigable hard-tipped pen.

Technology contents of the present utility model: comprise that penholder inside is provided with the rubber-like pen core, simultaneously, the point cover front end that the penholder head connects is provided with elastomer, and point cover rear end is provided with hard part, and hard part is provided with internal thread and penholder thread connection.

Described point cover is by the quadric injection mould of point cover front end elastomer with point cover rear end hard part formed.

Described point cover front end elastomer is working of plastics with point cover rear end hard part, with the injection moulding of dijection machine, finish first penetrate the hard part injection molding after, form elastomer joining with its hot pressing injection that is the second moulding die of penetrating or part moulding die carry out TPR, TPE elastomeric material again with it.

Described rubber-like pen core, the oil pipe and the connector of pen core are made by plastics such as PP.

The beneficial effects of the utility model are, because the point that penholder connects cover front end elastomer has elasticity, make that nib, flexiblely departs from the penholder axis with understanding certain amplitude when writing, like this, nib ball or nib become soft with contacting of paper, make to write more smooth and easyly, and feel is more comfortable, alleviate greatly and write intensity, and simple in structure; Simultaneously, the elastic strength that the point that connects when penholder overlaps is not simultaneously, and point overlaps the whole elasticity that has, or only be located on the part angle when flexible, the angle nib of writing that these are different has different elasticity, and some angle do not have elasticity, and it can satisfy different users or same user and writes under the condition the flexible different requirements of nib in difference, can also not have freely to change between the flexible common hard-tipped pen at resilient spring pen of nib and nib simultaneously.And elastomer can effectively firmly connect, and attractive in appearance with penholder or thread connector.

(1) is point cover elastomer among the figure, and (2) are point cover rigid plastics spare, and (3) are penholder, and (4) are pen core, and (11) are point cover elastomer, and (22) are point cover rigid plastics spare, and (12) are point cover elastomer, and (23) are point cover rigid plastics spare.

The specific embodiment:

Embodiment one, and with reference to Fig. 1, Fig. 2, shown in Figure 3, point cover front end (1) is an elastomeric material, and point cover rear end (2) is a rigid plastics.First penetrate the injection mo(u)lding of point cover rear end rigid plastics spare (2) after, it is the quadric injection mould that the second moulding die of penetrating point cover front end elastomer (1) carries out, described point cover rear end rigid plastics spare (2) is provided with internal thread, and (3) are penholder, and (4) are the pen core that oil pipe and connector are made by the PP plastics.

Embodiment two, and shown in Fig. 4,5, point cover front end (11) is an elastomeric material, and point cover rear end (22) is a rigid plastics, and point cover rear end (22) is provided with internal thread.

Embodiment three, and shown in Fig. 6,7,8, point cover front end (12) is an elastomeric material, and point cover rear end (23) is a rigid plastics.First penetrate rigid plastics (23) injection molding after, be the biphasic injection that second point cover front end (12) the moulding die of penetrating carries out, point cover rear end (23) is provided with internal thread.Because point cover front end has only the elastomeric material that is of half, the angle nib of writing that these are different has different elasticity, and some angle does not have elasticity, it can satisfy same user and writes under the condition the flexible different requirements of nib in difference, can also not have freely to change between the flexible common hard-tipped pen at resilient spring pen of nib and nib simultaneously.

Above embodiment is only for the usefulness that the utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from the utility model spirit and scope, can also make various conversion, change all technical schemes that are equal to and also should belong to category of the present utility model, should limit by each claim.
